Safety Warning

Full Product Description

The EP pneumatic rod seal/wiper and guiding element for piston rods of pneumatic cylinders performs three functions: sealing, wiping and guiding. The Ultrathan® compound is characterized by extremely high wear resistance. The multi-component design of the EP profile with an aluminum cage enables very easy installation by axial press-fit into the cylinder head.

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Multi-functional element: seal, wiper and guiding element.
• Extreme wear resistance.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Simple fabrication of the housing.
• Short radial assembly depth.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve favorable friction coefficients and long service life.
• Multi-functionality provides warehousing cost benefits.

Range of application:
Pneumatic cylinders
